Tol all whom #may concern:

`Be lit `k`I`io'vvn-th.`aty I, CHARLES 'MAURICE Piiaoiiaf, a citizen ofthe United States5and a resident ofSouth Orange, `county of IEsseX, and State of New Jersey, have invented tion tdWatchmens cloc s.

'To -the accomplishing of the above objects and to such others -as may-hereinafter appear, theinventio'n comprisesin a Watchmans clock a seriesof impression members Anormally Alocked 'against movement, a key barrel arranged to -hold a `key which 'is adapted to unlock and actuate said impressionme'mbers; the llocking means for said*` impression members" being arranged to op- .er'ate as soon as the key is withdrawn.

'-While thejinventin Iis Vto be described with particular reference'to-thedetails of construction, it is not "tobe considered as limitedfthereto, as many changes can be madef-andstill'ffall within the scope olithe` -invention setforth in the appended claims.

"Fig9 is a perspective view of the key.

In thedrawings, l designates the ease of the Clofck, 2 y the cover `thereof, v3 the main arbornhch sfdrven, les is Customary, by

e suitable clock work, not shown, and `4 Vdesignates an impressibl'e dial of paper or some like material mounted on said arbor to rotate therewith. The dial commonly has printed upon it suitable lines and numbers denoting hour spaces.

Adjacent the movement plate 6 is a removable plate 7 which supports a stationary printer or stamp plate 8 the underside ofthe upper end of which is cutaway to permit of the edge of the dial 4 passing underneath the same. Directly underneath the stamp plate 8 is situated, in the plate 7 a longitudinal slot 9, through which slot the marking arms of one or more impression members 10 may project to force the dial .4 against the underside of the stamp plate 8 and so mark the dial. The marking plate 8 has on its underside suitable matrices as shown in .'Fig. 3, which correspond to the numerals on the arms of ythe impression members 10 as shownin Fig. t.

The impression members 10 are in the prese-nt instance six in number, although more or less can be used as desired depending upon circumstances` The impression members l0 are arranged side A'by'side and are pivoted at one end upon a krod 1l the ends oi which are secured to the depending side plates l2 andl secured to theunderside of the plate 7 throughthemedium of the cross plates l'by means of screws 15.

Adjacent the free ends ofthe impression members l0 is located a key barrel 16ro'- tatably mounted at each end in the depending plates l2 and 1?).` In the presentinstance thekey barrel is provided with three longitudinalslots, a, b, and c, adapted-to be entered by thel corresponding Wards, ,fe, j", and g, of the key 22.

The lkey-barrel 16 lis normally held in lockedpositionby means of a lockiii pin 28 `the free end of which engages thes ot a. The locking-pin 231is slidably mounted togetherwvithja spring 24 in a block 25 secured to the side plate l2.

Thel impression members 10 are normally held in locked position by means of a locking plate 26 provided with la locking lip 27 which engages the locking shoulders 28 adjacent thepivoted end of every impression member. The locking platev 26 isy in if the present instance secured to a cam plate 29 which supports thessame through (the medium ofa pivotpin v30 secured to the side plate 13. Thev locking plate 26 is provided with an arm 3l the outer end of Which is connected to a cross rod 32 secured to the side plates 12 and 13 by means of a spring- 33.

The spring 33 acts to force the locking lip 27 of the locking plate 26 upward into engagement with the shoulders 28 of the impression members 10 which are all forced downward through the medium of a flat spring 34 as shown in F ig. 5.

Each impression member 1() is provided with lan upwardly projecting arm 35 and the top of'each arm is provided with a numeral so as to mark the dial l whenone or more of the projecting arms are forced into contact therewith.

When it is desired to mark the dial 4 at any given time a suitable key 22 is inserted in the key ,barrel 16, the inclined end of the ward cl operating to push the end of the locking pin 23 out of the slot a so as Vto release the key barrel as shown in Fig. 5. The key and vkey barrel vare then turned in a clockwise direction so that the ward f of the key will engage the cam face. 37 of the cam plate 29 to force the locking hp 27 out of engagement with the shoulders 28 thereby releasing all of theI impression members 10. The ward e of thekey is then free to force one of the impression members 10 upward so that the numeral on its upwardly projecting arm 35 will make an impression on the dial e by being forced thereagainst, as shown in Fig. 7. l/Vhenthe key is then turned in a counter-clockwise direction the ward 7E on the key acting against the cam face 37 holds the locking lip 27 against the action of the spring 33 until the impression member 10 previously operated is returned to its normal position with the other impression members 10 by the' action of Ithe spring 311, so that when the ward f on `the key is out of engagement with the cam face 37 the locking lip 27 will again engage the shoulders 28 of all the impression members, thereby locking the same.

rlhe key barrel 16 is preferably limited in its movement in a clockwise direction by means of a safety block 38 suitably secured to the outside of the key barrel by means of suitable screws 39. The movement of the key barrel in a counter clockwise direction is limited by the ward g of the key, which is adapted to engage suitable shoulders-41 formed on the free ends ofeach of the impression members 10. The ward g 4of the key acts on the shoulders 11 of the impres-y sion members to force the same into locked position, as vshown in Fig. 5, if for any reason the spring 34 fails to act. If desired the spring 34 may beomitted as the ward g on the key will act to force the impression members into locked position. llt will also be seen that by reason of the position of the ward g on the key, the key cannot beremoved from the key barrel until all of the impression members have been forced into locked position.

By providing different keys with different wards corresponding to the ward e any individual impression member or group of impression members can be operated to mark tlfedial.

' The key barrel 16 is preferably provided with a central partition 4A adapted to lit the slot ll5 in the key. By providing different key barrels in di iferent clocks with varying lengthsl of partitions and varying positions of guards y(not shown) in the key barrel different keys will be requiredin each case.

It is practically impossible to pick and operate the -impression members by means of a skeleton key or similar instrument other than a key made especially for the purpose, for the reason that the impression members are locked and the springs 33 and 34 are always operating to keep .the same in locked position and if an instrument can be used to release the locking plate 26 it will fly into' locked position before the impression members can be operated.

To each clock there 1s provided aplurality ofkeys similar to the key 22, the number of keys depending upon the number of places the `watchman is` required to coverwin` his rounds, each place vbeing provided with a keyusually secured to the Wallin a suitable box. These keys are usually all made alike with the exception of being provided with differentseries of wards@` so that each key will operate a vdi'erent series of impression members 1,0 so thatthe impression made byy each key onthe diall willdesignate not only the time but the placeof recording.

1What I claim is: y 7

3. In a watchmans clock a key-actuated mechanism comprising in combination a record carrier and markin mechanism, one of which is movable wit respect to the other, said marking mechanism comprising means for marking upon the record, including one or more impression members, means for locking said impression members, and a key having at least two sets of wards, one set of wards being arranged to act on one side of said impression members to unlock and actuate one or more of said impression members, the other set of wards being arranged to act on the other side of said impression members to return said impression members to locked position.
